基于门控柜的站台门联动方案分析

Analysis of Platform Door Interconnection Scheme Based on Door Control Cabinet

对常州轨道交通信号与站台门接口方案和传统接口方案进行了比较分析,重点介绍了信号系统门控柜与站台门之间的接口方案。车载信号设备通过车地无线通信直接向门控柜发送控制命令,取消中间部分继电器控制环节,精简了接口设备,缩短了系统反应动作时间,有效提高了开关门的效率。同时,门控柜采用冗余配置,提高了整个系统的运行效率及可靠性。

The signal and platform door interface solution of Changzhou Rail Transit is analyzed and compared with the conventional interface solution.Interface solution between signal system door control cabinet and platform door is expounded.On-board signal system sends control commands directly to the door control cabinet(SPSDC)through vehicle-ground wireless communication.The intermediate relay control part is canceled and the interface device is simplified.The system reaction time is reduced and the efficiency of door opening and closing is effectively improved.At the same time,the door control cabinet adopts redundant configuration,which improves the operation efficiency and reliability of the entire system.
